Let's divide 54436209 by 531
Our goal is to divide 54436209 by 531.

Step 1:
The number 531 fits into 5 0 times, leaving a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Bring next digit (4) of the dividend behind the 5 and repeat the process: 54 / 531

Step 2:
531 can be fit into 54 0 times, resulting in a remainder of 54.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 54, we end up with 54.
Take the next digit (4) from the dividend and append it to 54, then repeat: 544 / 531

Going ahead to step 3:
The number 531 fits into 544 1 times, leaving a remainder of 13.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 531 from 544 to get 13.
Include the next digit (3) from the dividend after 13, then repeat: 133 / 531

On to step 4:
531 can be fit into 133 0 times, resulting in a remainder of 133.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Subtract 0 from 133 to get 133.
Include the next digit (6) from the dividend after 133, then repeat: 1336 / 531

On to step 5:
531 goes into 1336 2 times with a remainder of 274.
The number 2 becomes the next digit in our result. 
Result so far: 102.0
Deduct 1062 from 1336 and we're left with 274.
Include the next digit (2) from the dividend after 274, then repeat: 2742 / 531

On to step 6:
531 can be fit into 2742 5 times, resulting in a remainder of 87.
Record the quotient 5 as the next digit in the result. 
Result so far: 1025.0
Subtracting 2655 from 2742 leaves us with 87.
Bring next digit (0) of the dividend behind the 87 and repeat the process: 870 / 531

Going ahead to step 7:
If we divide 870 by 531, we get 1 and a remainder of 339.
The next digit of our result is 1. 
Result so far: 10251.0
If we subtract 531 from 870, we get 339.
Grab the next digit (9) from the dividend, add it to 339, then carry on: 3399 / 531

Step 8:
531 goes into 3399 6 times with a remainder of 213.
Record the quotient 6 as the next digit in the result. 
Result so far: 102516.0
If we subtract 3186 from 3399, we get 213.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2130, and continue the process.

Going ahead to step 9:
531 goes into 2130 4 times with a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 102516.4
Subtracting 2124 from 2130 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 10:
The number 531 fits into 60 0 times, leaving a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 102516.4
If we take 0 away from 60, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 11:
If we divide 600 by 531, we get 1 and a remainder of 69.
Put 1 as the next digit of the answer. 
Result so far: 102516.401
Subtract 531 from 600 to get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Let's proceed to step 12:
The number 531 fits into 690 1 times, leaving a remainder of 159.
The next digit of our result is 1. 
Result so far: 102516.4011
Subtract 531 from 690 to get 159.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1590, and continue the process.

The final result is 102516.4011 with a remainder of 0.00159.
